Rather than spending a lot of time building a router table, I recommend making a Samurai Carpenter's router jig [1] which is far simpler to make, and more useful in most woodworking joinery tasks. I spent many evenings making a nice router table, and I've used it maybe a dozen times. The Samurai jig, on the other hand, I use all the time. Mostly cutting half lap joints in two-by material, but also for notching and general routing. It is much easier to use a router when you can the bit cutting. With a router table you have to rely on the fence for making accurate cuts. (A good fence is a mandatory accessory for a functional router table)
